Question

earth’s place in the universe
calculate it
at this point, you will work out the distance of each of the planets to the sun in astronomical units (au). complete the data table below. you will be dividing.

planet	distance to the sun (millions km)	distance to the sun astronomical units (au)
venus	108
earth	149	1.00
mars	228
jupiter	780
saturn	1437
uranus	2871
neptune	4530

you need to calculate the au for each of the planets. earth is already done and the example below shows how to work out the au for mars.
earth in km 149 → 1 au earth in au
mars in km 228 →? au mars in au
planet distance / 149 = planet distance in au
this line means to divide!
228 / 149 = 1.53 au

Explanation:

Step1: Recall conversion method

To convert distance in km to AU, divide by Earth - Sun distance in km (149 million km).

Step2: Calculate for Mercury

$\frac{57}{149}\approx0.38$

Step3: Calculate for Venus

$\frac{108}{149}\approx0.72$

Step4: Calculate for Mars

$\frac{228}{149}\approx1.53$

Step5: Calculate for Jupiter

$\frac{780}{149}\approx5.23$

Step6: Calculate for Saturn

$\frac{1437}{149}\approx9.64$

Step7: Calculate for Uranus

$\frac{2871}{149}\approx19.27$

Step8: Calculate for Neptune

$\frac{4530}{149}\approx30.40$

Answer:

Planet	Distance to the Sun (millions km)	Distance to the Sun astronomical units (AU)
Venus	108	0.72
Earth	149	1.00
Mars	228	1.53
Jupiter	780	5.23
Saturn	1437	9.64
Uranus	2871	19.27
Neptune	4530	30.40
